Title: Ghost cancellation
Inventor: PATEL CHANDRAKANT BHAILALBHAI
IPC: H04N5/21
Filed: 1992-09-04
Abstract: A new technique for channel characterization for Advanced Compatible TV (ACTV) broadcasting systems is hereby proposed that conforms to the current practice of transmitting a ghost cancellation reference (GCR) signal during the vertical blanking interval (VBI). A copy of the GCR signal is stored at the receiver, and is used to extract the effective ghost channel parameters via digital signal processing techniques. A pair of equi-length, binary (+/-) sequences is said to be complementary if the sum of the linear autocorrelation functions of the sequences is identically zero for all shifts other than zero, and provides a high correlation gain at zero shift. Such sequences can be sequentially transmitted on the allotted VBI line in the appropriate fields, along with pairwise constant signals in the corresponding fields of a basic eight field sequence. To conform to the positivity constraint of the transmitted signal for NTSC compatible systems, each complementary sequence is transmitted on a pedestal. At the receiver, the effect of the common constant signals are first removed by subtraction and the resultant signals are correlated with each of the two complementary sequences. The output of the correlators are added to directly yield estimates of the channel coefficients. <IMAGE>

Title: Method of operating a computer in a network.
Inventor: ROPER MICHAEL IAN
IPC: H04L12/18
Filed: 1992-11-07
Abstract: A computer forms a node in a network, consisting of computer nodes linked together into a minimum spanning tree topology. When a computer receives a message from a first node linked to it, it forwards the message to other nodes linked to that computer, as well as storing information about the message. As replies are received from the other computers, they are stored and collated together, to allow the computer to send just a single reply message back to the originating node based on the collated replies. This single reply is in turn collated at the next node, with the result that network traffic is reduced. <IMAGE>

Patent GB-2283120-A (GB)
Title: Memory circuit
Inventor: HOWARD DAVID WILLIAM
IPC: G11C29/04
Filed: 1993-10-13
Abstract: A memory circuit, in which test data are compared with stored data, comprises a plurality of memory cells 300 each having two complementary data outputs indicative of a respective stored bit of the stored data. The two complementary outputs are selectively interchanged, by switch means 320, in response to a respective test bit of the test data A[31:11]. An output signal is then generated (e.g. by a sense amplifier 330) in response to the relative polarities of the two complementary data outputs. The output signal is indicative of whether the stored bit is equal to the test bit. Where a multi-bit word is stored in a plurality of the memory cells, the output signals generated by a comparison of each stored bit of the multi-bit word and respective bits of the test data are combined by, for example, an AND gate 350. The output of the AND gate indicates whether the test data matches the stored multi-bit word. The switch means 320 may include p-channel transistors (400, 410, 420, 430, Fig 4) <IMAGE>

Title: Storage of missiles by reversibly solidifying their fuel
Inventor: KELLERER HELMUT
IPC: F02K9/42
Filed: 1994-01-20
Abstract: In the storage of liq. propellant-fuelled missiles, esp. equipped with ramjets, the novelty is that the or each liq. propellant is modified so that it forms an electro-rheological fluid which is reversibly solidified by alternating voltage application, the solidified state being maintained by maintenance of the voltage during storage.       Also claimed is a similar storage method in which the liq. propellant is modified to have a liq. crystalline phase in a specific temp. interval, the lower limit (melting pt., solidification pt.) of which is below the lowest fuel temp. expected during use of the missile.       USE/ADVANTAGE - E.g. for missile storage on board ship. The method provides safe and problem-free missile storage, has acceptable energy costs, allows rapid re-liquefaction of the propellant and retains the advantages of liq. propellants.

Title: Circuit breaker
Inventor: KITAMURA TAKASHI
IPC: H02H3/33
Filed: 1995-05-09
Abstract: Circuit interruption is executed in the event of faulty connection of a distribution line, thereby improving safety. Contacts 3, which are opened and closed by drive mechanism 4, are inserted in a main current path between power-supply-side terminal area 1 and load-side terminal area 2. Neutral-line potential response means 10 between legs of the main current path are equipped with a series circuit containing energizing coil 12 and thyristor SCR1, while resistor R2, capacitor C1, and diode D2 are connected in parallel across the gate and cathode of thyristor SCR1. Furthermore, resistor R2 is connected through Zener diode ZD to main-current-path neutral-line-side lead N. In the event of reversal of live and neutral connections, or an open neutral, a potential difference is generated between neutral-line-side lead N and ground connection area 7. As a result, Zener diode ZD passes current, turning ON thyristor SCR1 and opening contacts 3. The circuit also responds to excessive current, and may include an earth leakage detection transformer. <IMAGE>

Title: Method of damping control oscillations of a motor vehicle traction control system
Inventor: FISCHLE GERHARD
IPC: B60K28/16
Filed: 1995-05-22
Abstract: A method of electronic traction control for motor vehicles is proposed by means of which the undesired traction control oscillations - such as a pull-away tramping effect and/or drive train oscillations - are damped and, therefore, substantially avoided. For damping the pull-away tramping effect an interchange of the low-adhesion wheel to be controlled from one driving wheel to the other should be undertaken only when (1) the difference DS between the rotational speeds of the previous high-adhesion wheel and the previous low-adhesion wheel is greater than a threshold value, and (2) one of the two alternatives specified in box 3 are not satisfied. Additionally or alternatively, when drive train oscillations are recognized (22, figure 2), the threshold value is raised. <IMAGE>

Title: Process and device for adaptive scanning of halftone originals
Inventor: KUZNETSOV JURY VENIAMINOVICH
IPC: H04N1/40
Filed: 1994-11-16
Abstract: In the proposed process for the adaptive scanning of a halftone original, the presence or absence of an outline (1) in the relevant sector (E) of the original is ascertained. If there is no outline (1), the elements of the corresponding sector of the substrate are made dark or light depending on the result of a comparison between the value M E of the optical parameter of the relevant sector of the original with the primary weighting values (P 1 ) of the elements which ensure smooth tonal transfer. If an outline (1) is present, the relative degree of detail (q) of the relevant sector of the original is ascertained, secondary weighting values P 2 are assigned to the elements to ensure geometrical accuracy in the transfer of the outline, and tertiary weighting values P 3 are calculated from the formula P 3 = qP 2 + (1-q)P 1 . The elements are made light or dark depending on the results of a comparison between their tertiary weighting values and the value M E of the optical parameter. In another variation of the process, if an outline (1) is present in the relevant sector (E), the values M 1 = M E + q(M max -M E ) and M 2 = M max -qM max -M E ) are calculated for this sector, M max being the maximum value of the optical parameter. The elements of the substrate are made light or dark depending on the result of a comparison between their primary weighting values P 1 and the value M 1 and/or depending on the result of a comparison between their secondary weighting values P 2 with the value M 2 . The proposed device for adaptive scanning comprises a video signal source (2), sources (7, 8) of the primary and secondary weighting values, a unit (10) for determining the relative degree of detail and a unit (9) for controlling the beam interrupter which exposes the elements of the substrate (5). According to one variant, the control unit (9) comprises a series of computing units (40) matching the number of elements within the relevant sector for forming the tertiary weighting values of the elements, a switch (42) and a comparator (43). In a second variant, the control unit (9) comprises: a computing unit (48) for obtaining the M 1 and M 2 signals; two switches (49, 50) for switching in accordance with the primary and secondary weighting values; two comparators (51, 52) which compare the primary weighting values with the M 1 signal, and the secondary weighting values with the M 2 signal; and an OR circuit (53) for combining the output signals from the comparators (51, 52).
